L1: The signal-twist pair connecting ADSL Loop Extender to DSLAM.

L2: The signal-twist pair connecting ADSL Loop Extender to Modem.

2. Resistance and distance demand

The recommended installation conditions are as follows:

(1)24 AWG(0.5mm) twist pair

The Demand about Resistance and Distance of 24AWG:

(2)26 AWG(0.4mm) twist pair

The Demand about Resistance and Distance of 26AWG:

Note: The switches on the PCB are default setting on “LOW” when ex-work.

Physical Structure

• AER800-1PL: Stand-alone 1 port unit.
• AER800-4PL Box: A Box for up to 5 AER800-C1PL cards.
• AER800-8PL Box: A Box for up to 9 AER800-C1PL cards.
• AER800-C1PL: A one port ADSL Loop Extender designed to be inserted into the backplane of any AER800-PL enclosure

2.  AER800-4PL Box

AER800-4PL Box

The AER800-C1PL modular card system allows for plug and play installation of new subscribers. Wiring terminals on the backplane connect to the existing copper loop plant.

3.  AER800-8PL Box

AER800-8PL Box

The backplane of the AER800-PL series enclosures contain wiring terminals for connecting the extender to the existing loop plant. “CO” connects the signal line from the DSLAM to AER800-C1PL; “CPE” connects the line to the customer modem

4. AER800-C1PL Subscriber Card

LED lights indicate power status. Additionally, the AER800-C1PL cards contain DIP switches designed to operate with different CO telephone switches, please follow the following picture:

As you can see, the switches are default setting on “LOW” when ex-work, which requires that the distance L1 from CO to the ADSL loop extender must be longer than 2.8km on 24AWG or longer than 2.3km on 26AWG. At this time, the ADSL loop extender’s working current is 4.2mA.

In case that L1 couldn’t be longer than 2.8km on 24AWG or couldn’t longer than 2.3km on 26AWG, you can set the switched to “HIGH”. At this time, the ADSL loop extender’s working current is 6.2mA, and two things are needed to be noted:

1. L1 must be longer than 2.4km on 24AWG or longer than 2.0km on 26AWG;

2. The threshold of telephone switch is higher than 6.2mA.

Installation Procedure

1. Unpack

When unpacking the equipment, be sure to check the contents of the packaging for completeness against your purchase order. Notify your supplier immediately if any items are missing.

Note: Please save packing material. All equipment returned must be packed in the original packing material.

Be sure to inspect the equipment for shipping damage, including bent or loose hardware, and broken connectors. If the equipment appears to have been damaged in transit, please contact your supplier.

2. ADSL Loop Extender Installation

(1) The AER800-1/4/8PL Box can be installed in a junction cabinet, pedestal, or pole mounted via the supplied mounting brackets. Once mounted, ground the unit via the supplied grounding screw on the bottom outside of the box.

Attention: Copper-core wire with no less than 2.5mm2 (13 AWG) diameter is required as ground wire. One end of the wire should connect to Loop Extender’s ground terminal. The other end of the wire should connect to a good grounding point. Grounding reliability is the best way to protect the unit against lightning damage.

(2) Insert the AER800-C1PL card into the AER800-4/8PL Box.

(3) Connect the line from the DSLAM to the “CO” terminal, and connect the line linked to the customer’s modem to the “CPE” terminal. Once the “CO” pair is connected, the power LED will come on to indicated the AER800-C1PL card is operational.

(4) After confirming that all the twist-pair cables are connected correctly, and the AER800-4/8PL is securely installed, the extender will function 10 seconds after power is steadily applied.

Attention:

“A” and “B” represent tip and ring of the twisted-pair. No polarity.
